"Blake's been planning to write a tell-all on Amy since she became famous. When they were together he'd film her, but there are many hours of footage and photos he hasn't released."

The paper claims that money will be the big factor in Blake writing the book, especially since he's contemplated doing so for a while.

Amy was married to Blake from 2007 until their divorce in 2009. The two had a rocky relationship before and during the marriage. Both battled drug and alcohol addictions, and Blake admitted that he was the one who introduced Amy to heroin and crack cocaine.

Blake is currently in jail for armed robbery and a firearm offense. Amy was found dead on July 23 at her North London home, but the official cause of death has not been determined yet.

The Sun is also reporting that Amy's home has been robbed, most likely by an acquaintance. Find out how the singer's father Mitch Winehouse reacted to the news after the jump.

Approximately twenty people have had access to Amy's house since she passed away, and now her management team says that unreleased tracks, lyric books, letters and one of Amy's favorite guitars have gone missing.

A source close to Amy told The Sun:

"This is such a sickening shock to the family. That someone would stoop so low. They can't get their heads around it. Mitch is livid. The family, record label and management are months away from deciding what to do with any unreleased music. For that to be taken out of their hands is horrible."
